New conditions forged gearbox housing Precision differential housing for automotive systems
PRODUCT OVERVIEW
Our new forged gearbox housings and differential cases are precision-engineered for maximum durability in automotive and heavy equipment applications. Manufactured through advanced hot forging processes, these components provide superior structural integrity compared to cast alternatives, ensuring reliable performance under extreme torque and load conditions.
KEY FEATURES & BENEFITS
✔ Premium Forged Construction – High-strength alloy steel (4140/4340) for exceptional impact resistance and fatigue life
✔ Precision Machining – CNC-machined to ±0.01mm tolerances for perfect gear alignment and reduced vibration
✔ Heat-Treated Durability – Hardened to HRC 32-50 (customizable) for wear protection in harsh environments
✔ Leak-Proof Design – Integrated sealing surfaces prevent lubricant leakage in differential/gearbox systems
✔ OEM/Aftermarket Fit – Direct replacements for trucks, construction equipment, and performance vehicles
